ACM CHI 1995 - The DragMag Image Magnifier

Computer image magnification often results in the loss of the contextual information. Two image magnification prototypes are presented that solve this problem. IN both the base image is shown at all times with lines connecting the magnified region on the base image to the magnified image. Both prototypes allow for smooth pan, scroll, and zoom of large 2D images with both coarse and fine translation movements. The second design implements a magnifying glass metaphor whereby the degree of magnification is controlled by the distance of the enlarged image to the magnified region of the base image.
